AS5147P − Detailed Description
UVW Commutation Interface
The AS5147P can emulate the UVW signals generated by the
three discrete Hall switches commonly used in BLDC motors.
The UVWPP field in the SETTINGS register selects the number
of pole pairs of the motor (from 1 to 7 pole pairs). The UVW
signals are generated with 14-bit resolution.
During the start-up time, after power on of the chip, the UVW
signals are low.
Figure 33:
UVW Signals
Figure 33 shows the UVW signals for a magnet rotating
clockwise, as viewed from above the magnet and the
AS5147P.The (DIR=0) bit can be used to invert the sense of the
rotation direction.
